Model DC7144A, AM1 

DC7144, M1 through M3 

Dual Directional Coupler 

400 Watts CW 

0.7GHz–4.2GHz 

The Model DC7144A is a dual directional coupler with excellent frequency range and power handling capability.  The 

wide range assures flexibility in coupling medium power amplifiers to oscilloscopes, voltmeters, power meters, spectrum 
analyzers and other measuring instruments.  The dual directional design allows the user to monitor both forward and 
reflected power, a much needed characteristic in RF susceptibility testing for amplifier overdrive protection, field control 
and load protection.  Low insertion loss allows efficient coupling to the load. 
The Model DC7144A is uniquely suited for use with our “S” series microwave power amplifiers, other amplifiers operating 
within this frequency and power range, and our PM2003 power meter.
